Hi crankytoe,
as you have probably read in all the posts above, they will never let go. The Watchtower Society preaches, that interested ones have to brought to the organization as soon as possible.........the meetings are their lifeline ........ it's a MUST.
You will soon find out that what you are studying is not the Bible, but the Society's interpretation of it. You will be studying their literature, as in the book you are studying now, the book they study in their bookstudy (don't know which one it is at the moment), their Watchtower, their books for the Service Meeting and so on.....for any research, of course, they will use many other Watchtower books.
They will make you believe, that their's is the only true religion and that you will be damned if you don't join......I don't want to discourage you or tell you not to study with them, but beware of what this "study" all includes, if you were to do it their way......
Bible study 1 hour plus 30 minutes preparation for it
Bookstudy 1 hour plus 30 minutes prepartaion for it
Sunday Meeting 2 hours plus 30 minutes preparation for it (minimum)
Theocratic Meeting almost 2 hours plus 1 hour preparation for it
and to go along with the national average of monthly preaching, which is about 10 hours a month, at least 2 hours a week, plus preparation for 30 minutes or so.
That alone is 11 hours every week, not counting the driving time from and to the meetings and the time spent there "visiting".......and I'm sure you heard about conventions and assemblies.
So beware!
